According to the source, the former Disney Channel star broke up with his stylist love "a while ago." Now, he seems focused on moving forward -- LaBeouf, 26, was spotted cozying up to a mystery blonde at L.A.'s Magic Castle Saturday night.

LaBeouf first met Pho in early 2011 during a trip to a karaoke club in L.A.'s trendy Echo Park neighborhood. In an interview with the Los Angeles Times that summer, the famously hot-tempered Transformers star credited his then-girlfriend with helping him grow up a little -- which included encouraging him to expand his culinary palate.
